Abstract

Effects of instant coffee on weight, plasma lipids, leptin levels, and fat cell size in high-fat diet-fed rats were investigated, Twenty-four male Sprague-Dawley rats, fed experimental diet containing 40% total dietary fat and 0, 0.6, 1.2, and 2.4% (w/w) instant coffee for 6 weeks, were divided into four experimental groups (n = 6). Feed efficiency ratio of 0.6% coffee group was higher than control group. Weight gain, organ weights, free fatty acid level, and fat cell size were not significantly different among groups. Triglyceride, total cholesterol, HDL-cholesterol, and leptin levels in plasma were significantly higher in 0.6% coffee group than control group. No significant difference in feed efficiency ratio, triglyceride, and leptin levels were found between control and 2.4% coffee group. These results suggest instant coffee may not have effect on obesity.
